That's a complicated question that is not easily answered. If you're referring to god as Lucifer's father, then I would say that it's a combination of both.
Angels supposedly don't have free will - at least not in the sense that human beings are said to. That being said, if free will was not an option, how did Lucifer fall?
Cultures throughout history have believed in the balance. Light cannot exist without dark, good cannot exist without evil, etc. In that case, god created Lucifer for a specific purpose - to be his adversary (not his enemy). If god is truly omniscient like believers claim, then he knew what would happen and created Lucifer anyway - perhaps because he realized that by having an opponent, others would have more of a reason to believe in (and therefore worship) him.
